Abstract

Abstract The structure of mature epidermis and the ontogenetic pathway of mature stomata in some species of the family Gentianaceae, viz. Canscora decussata, C. diffusa, Exacum quinquenervium, Faroa pusilla, Neurotheca loeselioides, Sebaea brachyphylla and Swertia mannii are described. Ontogeny of stomata is shown to be eumesogenous in C. decussata, C. diffusa, N. loeselioides and S. brachyphylla , mesoperigenous in E. quinquenervium and F. pusilla and euperigenous in S. mannii . Juxtaposed contiguous stomata have been observed in C. decussata .
